These are really nice. bought some at glentress for the first time this week. 6 sort of squidgy cubes. nice tasting. felt good riding and ate these near the end of the ride plus water. seemed to recover well (but that might have been the haggis sandwich in Jedburgh of course)!
The strawberry ones are great for topping up your electrolytes. Keeps the cramps at bay on those long rides or on the really hot days when your fluid intake is high.
Not cheap though !
